Sagot :

x=number of students at Marita's high school last year
98%=.98
.98x=1170
x=1170/.98
x=1194

Answer:

1193

Step-by-step explanation:

If the number of students decreased to 98% of last years total, the total students decrease by:

[tex]100-98=2[/tex]

The amount of students decreased by 2% from the previous years total. We can then determine the amount of students that we 2% of the current total. We first convert 2% into a fraction:

[tex]2/100=1/50[/tex]

Therefore:

[tex]1170*(1/50)=234/10=23.4[/tex]

So in order to get this years total we must add 23.4 to this years total:

[tex]1170+23.4=1146.6≈1193[/tex]

There were 1193 students last year
